SMOD: Suck My Own Dick. this is an action taken when your girlfriend starts to get on your damn nerves. it is usually brought about by constant bitching about your hair, your dirty room, lack of trips to fancy dinners, looking at another girl (even when she's your waitress), or anytime during her period. when the bitching crosses the threshold you finally snap and are no longer willing to put up with her rediculousness...even for some well needed ass.
